GEORGE S. FAULKNER,- OF INDIANAPOLIS, INDIANA.

Letters Patent No. 99,17 7, dated January 25, 1870.

IMPROVEMENT IN LOQM The Schedule refened to in these Letters Patent andmaking part of the same.

A I, GEORGE S. FAULKNER, of Indianapolis, in the county of Maiion, andState of Indiana, have invented certain Improvements in Drop-Box Motionof Booms, of Wh-ichthe following is a specification.

Nature and Objects of the Invention.

This invention relates to the drop-box movement of looms, having for itsobject to communicate positire motion to the boxes, as controlled by apattern- .Description ofthe Accompanying Drawings- Figure 1 is an endview of the loom-frame, h a\ing my improved mechanism for operating thedrop-boxes applied thereto; all the other parts of the loom being leftolf, to show the drop-box mechanism more clearly. v 1 Figure 2 is a sideelevation of the same end of the loom.

Figures 3 and4 are front and edge views, respectively, of thebifl'ircated lever D D detached, with a fompointed cam, thatit isdesigned to substitute for cam F, on the bottom shaft, in order tooperate the boxes, to accommodate themto a pick-and-pick molion oftheshuttle.

A is the frame of the loom; B, the lay; and Cythe vdrop-boxes, allconstructed and arranged in substantially the usual manner.

In order ltti-communicate positive motion to the shuttlc-boxes, Iconstruct a bifurcated lever, D D', having its fulcrum on a. stud-pin,E.

Vibratory motion is communicated to this lever by an eccentric, F, on.the lower or bottom shaft Gr ofthe loom.

From the upper end of the long arm D', a connecting-rod, H, extends,.toone arm of an elbow-crank, I. pivot-ed on the same shaft with thepattern-cylinder J,

To the other arm of the elbow-crank I, a hooked pawl, K, is-attached,which engages with the ratchet L, shown in dotted lines, iig. 1, andimparts intermittent rotary motion to the pattern-cylinder J.

The pins a', in the pattern-cylinder J, operate the lever M, and thelatter being connected, by cord N, to a pawl, O, attached to the longarm of bifurcated lever D D', lowers the pawl to engage with, .or raisesit to be Adisengaged from the ratchet I), shown in dotted lines in iig.l, on the cam-shaft Q.

The cams It, ou cam-shaft Q, aetuate lever S, to raise and lower theboxes O.

It will be readily understood, by those conversant with looms, that withthis arrangement, the patterncylinder J is actuated te control themovement of the drop-boxes C, andtlaat the lonly change in the movementof the boites requirechto use various-colored thread in weaving anyvariety of pattern, is to change the eccentric F to one likejthatrepresented in figs. 3

and 4, by which the movement of the bifurcated lever is doubled. f t

In order to double the movement of the drop-boxes, the two arms of the,bifurcated lever D D may be made as shown in figs. 3 and 4, so thatwhen used, as shown in figs. 1 and'2, the eccentric F will have to bemade wide on the face.-

Claim.

I claim, as my inventionrIthe bitinpated lever D D', and rod H,connecting said lever with, the crank Land the eccentric F ou the shaftG, ananged to give positive motion to the pattern-cylinder or chain J incombination with the pawl O, attached to the lever D D', and the cord Nand lever M, for giving the required motion to the cam-shaft Q, allarranged and operating substantially as and tor the purpose set forth.
